What is this?

[Black Widow97]

What is this bolted to my motor mount? I have never seen it before on any of my other cars. Both of my 95 and 97 Talon AWD, manual trans did not have it. This is a 95 Talon AWD Automatic. Is this something only automatics have? What does it do?

Thanks guys!

Its a funny thing...its actually sort of a counter weight to cancel out vibrations through the motor mount...I think its due to your car being an auto, not sure though

vibration dampner.

How does that thing dampen vibrations?

 

[TurboJimbo]

Its weird how it works but its works...by adding that thing, which is just weight, it helps to cancel out vibrations...the 350Z and EvoX have weights also...the EvoX has a pretty heavy one under the front bumper

Some how before the cars are released from the factory, there is a test thats done to them to find vibrations or something like that and they solve these vibrations by just adding weight to help blance things out...its hard to explain but I read about this once and it made perfect sense, haha

Hmm im a auto and my car doenst have one...

I have a 95 5spd AWD Talon and I have it.

That's gotta be a 2ga thing.

It is kinda a 2g thing because that is when they started applying them. At the factory during production they check each individual car for excessive vibrations and add the counter weights as needed. If the car doesnt have excessive vibrations then the weight isnt added on. I was stumblen around on the internet and found a bunch of useless info on dsm production process.

my Versa has something exactly like this...i too was stumped. I see these on all different cars i work on at work...most seem to be just light molded rubber bolted on.

The weights are not there to balance anything out, its because everything has a natural resonance when things start vibrating together at the same resonance you feel it. So manufacturers instead of re-engineering diff vehicle systems they add those weights to make it heavier thus causing the resonance to come in later and not causing a vibration, at least thats how it is described in my NVH classes

I had a friedn who used to work at Ricardo and he was in the vibration and dampening dept. And that was basically his job, a new vehicle would come out and it had a vibration or hum and they would do all kinds of tripped out test and fix the problem.
The vehicle would go back to the manufacture and put into production.

sorry wnet on a tangent, in short YES you are correct.

My car is a manual and had one. They fall off over time.

Alright, I had never seen one before untill this car. This is my 5th DSM and this is the first time I have seen one. Thanks for the info guys.
